STLLR Gold Provides its 2025 and Long-Term Plans and Introduces the Hollinger Tailings Project

Toronto, Ontario - Newsfile Corp. - February 3, 2025 - STLLR Gold Inc. (TSX: STLR) (OTCQX: STLRF) (FSE: O9D) ("STLLR" or the "Company") outlines its 2025 plans and long-term outlook for the Tower Gold Project ("Tower") in Timmins, Ontario, and the Colomac Gold Project ("Colomac") in the Northwest Territories ("NWT"), Canada.

The Company is also thrilled to introduce its Hollinger Tailings Project in Timmins, Ontario, highlighting its debut and outlining plans for 2025. Situated within the city of Timmins and conveniently close to existing processing facilities, the project stands out as a strategic opportunity. Recent changes to the Ontario Mining Act¹ ("Mining Act") simplify the permitting process to unlock the economic potential of reprocessing mine tailings while encouraging environmental remediation of legacy sites. With low capital requirements and a favourable gold price environment, the Hollinger Tailings Project presents significant upside potential for STLLR.

Keyvan Salehi, P.Eng., MBA, President, CEO, and Director of STLLR, commented: "We believe 2025 will be a pivotal year for STLLR. With a strong balance sheet supporting our plans, we are focused on advancing key projects. At Tower, we aim to deliver an updated MRE and PEA. InnovExplo² will oversee the completion of the MRE and G Mining Services will oversee the completion of the PEA. Both reports are progressing in parallel and will be disclosed simultaneously and under one technical report. Additionally, we will continue exploration in the Timmins area and progress environmental baseline studies to secure the necessary permits, as we advance Tower to shovel-ready status."

"We are enthusiastic about the potential of our Hollinger Tailings Project in Timmins. After months of preparation, we are now set to quantify its value. Recent updates to the Mining Act could position the project as a near-term cash flow opportunity at current gold prices, while furthering our environmental commitment to reclaiming this historical site."

"Located near existing processing facilities with available capacity, the project presents a promising opportunity for additional mill feed within the Timmins camp. In Q1 2025, we plan to conduct a tailings characterization program. Based on our findings, we will move forward with a mineral resource estimate and, if justified, a preliminary economic assessment. With minimal capital requirements, the Hollinger Tailings Project has the potential to be a game changer for STLLR Gold. Stay tuned for updates as we advance this exciting opportunity!"

"Looking ahead, our long-term vision is to bring our Tower and Colomac projects to shovel-ready status, with Tower as the priority due to its proximity to existing infrastructure. Our goal is reaching a shovel-ready stage for Tower within 36 to 48 months."

2025 Ontario Activities

• Updated Tower Mineral Resource Estimate ("MRE") and Preliminary Economic Assessment ("PEA") in H1-2025:

STLLR plans to release the Tower MRE and PEA together in H1-2025. The MRE will benefit from over 120 km of infill drilling and improved geological models. Verification of historical drilling at Garrison provides added confidence to the MRE data. The PEA will detail an updated mine plan and economics for Tower, showcasing optimized throughput and production.

• Exploration, Technical and Permitting Activities:

STLLR plans to drill 5,000-7,000 metres at Tower to enhance mineral resource confidence. The Company will initiate a metallurgical program as well as other studies that will drive Tower towards a pre-feasibility study ("PFS"). Additionally, STLLR will continue environmental baseline studies necessary for permitting.

• Hollinger Tailings Project:

The Hollinger Tailings Project, located in the southeast area of the city of Timmins, Ontario (see Figure 1), is where tailings from the Hollinger Mine were stored. The Hollinger Mine, which operated from 1910-1968, was at one time the world's largest gold mine. It produced 19 million ounces of gold at an average grade of 9.9 grams per tonne.³ An estimated 50-60 million tonnes of tailings were placed at the Hollinger Tailings Project. STLLR plans to conduct a 10,000-12,000-metre characterization program of the tailings, establishing a path forward for a potential mineral resource estimate. There is a 1.5% net smelter royalty on the potential gold content of the Hollinger Tailings Project property.

2025 NWT Activities

STLLR plans to install solar panels at Colomac, under a lease agreement with the Tłı̨chǫ Investment Corporation⁴, evaluate high-priority drilling targets, perform reclamation, and assess permitting activities. These site enhancements will enable more cost-effective, environmentally-conscious drilling and permitting in the future.

Long-Term Strategy

STLLR management is focused on advancing the Tower and Colomac projects to shovel-ready status, recognizing their potential to create value for the Company. Given its proximity to existing infrastructure, Tower will be the near-term priority. The Company estimates the following milestones for Tower:

• Deliver PFS in 24 months.
  
• Complete environmental baseline work and submit Federal Environmental Assessment ("EA") in 30 months.
  
• Deliver Feasibility Study ("FS") in 36-48 months.
  

Colomac's advancement is contingent on securing additional funding, with priority given to Tower's expenditures. The Company is continuing to evaluate various funding and strategic opportunities for Colomac.
